In fact it will be able to have a configurable level of redundacy. A redundancy of 1 is equivalent to RAID 5; a redundancy of 2 is equivalent to RAID 6; and higher levels of redundancy are supported. > > We are also trying to improve performance over replicate by using a new contention detection and locking mecanism, but no promises about that yet. > > We plan to begin internal tests soon.

If you have a replica count of 3, you can lose two boxes in that group and still have access to all your data. It's more like a 3-way RAID-1 than anything like RAID-6.

I already considered a replica count of 3 (and six servers at all, correct?), but the problem would still be that two hard drives from the same "replica group" were not allowed to fail at the same time. >>>> >>>>> Try doing a distributed-replica with a replica count of 3. Not really 'RAID-6' comparable, but you can have two nodes fail without outage. http://download.gluster.com/pub/gluster/glusterfs/3.2/Documentation/AG/html/sect-Administration_Guide--Setting_Volumes-Distributed_Replicated.html [5]On 3/29/12 10:39 AM, Pascal wrote: >>>>> >>>>>> Hello everyone, I would like to know if it is possible to setup a GlusterFS installation which is comparable to a RAID 6? I did some research in the community and several mailing lists and all I could find were the similar request from 2009 (http://gluster.org/pipermail/gluster-users/2009-May/002208.html [1], http://www.gluster.org/community/documentation/index.ph/Talk:GlusterFS_Roadmap_Suggestions [2]). I would just like to have a scenario where two GlusterFS nodes/servers, respectively their hard drives, could fail at the same time. Thanks in advance!
